HAN D-TRUCK.

SPECIFICATION forming part of Letters Patent No. 421,649, dated February18, 1890.

Application filed October 23, 1889- Serial No. 327,913. (No model.)

To all whom/it may concern.-

Be it known that I, JOSEPH ANNIN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Hand- Truck, of which the following is aspecification.

My invention is an improvement in the class of hand-trucks whose framesare constructed of iron or steel, and which are designed forheavy workin warehouses, foundries, machine-shops, &c. It is particularlydesirable that such trucks shall be constructed in such manner as topossess maximum lightness, strength, and durability without involvingunusualexpense in manufacture. To these ends I have devised the truckhereinafter described, and shown in accompanying drawings. It isespecially distinguished by an improved joint-connection between theside and cross bars of the frame and in an improved form of such bars,whereby great strength and rigidity, with minimum weight of parts, areobtained.

There are also other important features of construction, as will behereinafter pointed out.

In the drawings, Figure 1 is a perspective view of the truck, the wheelsbeing omitted. Fig. 2 is an enlarged vertical cross-section of theentire truck-frame, taken on line 2 2, Fig. 1. Fig. 3 is also anenlarged cross-section of a portion of the frame. Fig. 4 is aperspective showing one of the cross-bars detached and its connectionwith the side bars. Fig. 5. is an enlarged cross-section on line5 50fFig. 1. Fig. 6 is a perspective giving an under side view of a portionof the head or bill of the truck and its attachment to the side bars.

For convenience the larger or main parts of the truck-frame will beindicated by letters and details by figures.

The longitudinal or side bars a of the trucle frame are constructed ofangle-iron, the same being arranged with their narrower sides orhorizontal members 1 uppermost and the wider ones 2 vertical. It will benoted, also, that the angles of the said bars are outward, for a purposehereinafter explained. The inner sides or vertical members 2 of saidbars a are provided with slots 3, Fig. 4, to receive the 7 bar.

tenoned ends 4: of the curved cross-bars b, which are T-shaped intransverse section, and said slots are located below the top sides 1 ofthe bars a distance just equal to the thickness of the angle-plate ofwhich the bars a are made, so that the tenons 4 of the crossbars 19 wheninserted in the slots 3 will lie in contact with the under side of theupper members 1 of the side bars, as best shown in Figs. 2 and 3. Bolts5 pass through the said members 1 and the tenons at of the cross-bars1), thereby securing the parts rigidly together. The heads of the saidbolts are countersunk, as shown.

The tenons at are formed by notohing or cutting away portions of thesides of the upper membersof the cross-bars and also the end portions ofthe vertical or under side flange 6, (see Fig. 4,) thus leaving threeshoulders-to wit, two lateral shoulders and one vertical shoulder whichwhen the crossbars I; are attached, as shown in Figs. 1, 2, and 3, abutand bear against the vertical sides of the side bars a. Thus the latternot only tie the side bars a together, .but by means of the aforesaidshoulders serve as braces that hold the side bars rigidly apart. It willbe further noted that the tenons 4 rest or bear on the under edges ofthe slots 3, so that the bolts 5 are relieved of the strain incident tosupport of weight on the cross-bars b, and thus what would otherwise bea weak and defective connection is one of the strongest possible. Addingto this that the vertical members 2 of the cross-bars or exceed theupper members 1 in width, it becomes apparent that the capacity of thetruck-frame to resist the heaviest strain is carried to its maximum.

It is particularly important that the legs 6 shall be very light yetstrong, and be so attached to the truck-frame as to involve the leastexpense. I make each leg of one piece of fiat bar-iron, whose ends arebent laterally at a right angle, Fig.2, to adapt them to lie fiatagainst the vertical members of the side bars a and the under side ofthe tenons 4 of the front cross-bar b, so that they are not only bracedlaterally by the side bars a but are secured in place by the same boltsthat pass through the tenonsof said cross- About midway of their lengthboth members of the legs 0 are twisted axially to bring their lowerportions orfeet into a plane parallel to the transverse axis of thetruckframe, so that when the feet rest on the floor they have a bearingas broad as the width of the legs.

The cast-steel bill or nose cl of the truck is cast with notches orsockets at 7, (see Fig. 6,) to receive the ends of the upper mem bers 1of the side bars a, and also with a pendent flange 8, Fig. 5, extendingalong the inner sides of its horizontal portions. The axle pedestals orbearings 0 are secured in the angle of this flange 8 by the same boltsthat secure the bill to the side bars a, and the bill has a downwardprojection 10, which intervenes the ends of the pedestals, Fig. 6. Bythis construction the pedestals are braced laterally by the flange 8 andendwise by said projection 10. Thus at every portion of the truckframeprovision is made for the strongest resistance to both vertical andlateral as well as torsional strain by means of parts whose constructionis such that overweight is avoided.

I have described the preferred form of 0011- struction of the side bars;but under the general term angle-ironIwish to include variations thatinvolve the same principleas, for example, channel or T iron. Further, Iwish to cover changes of arrangement of parts, such as would result frominterchanging the side bars or transferring each to the place of theother, so that the angles of both bars shall be inward instead ofoutward, as in the present case, and bringing the vertical members 2 onthe outer side of the bars a. lVhile such arrangement is not expedientor advisable, yet it involves an advantage over certain othersheretofore adopted.

What I claim as new, and desire to secure i by Letters Patent, is

1. In a truek-frame, the combination, with the angle side bars havingslots in their vertical members, of cross-bars whose ends enter and havea bearing in said slots, and are bolted to the under side of the uppermembers of said side bars, substantially as shown and described.

2. In a truck-fra1ne, the combination, with angle side bars having slotsin their vertical members, of cross-bars whose reduced ends fit and bearin said slots and are bolted to the under side of the horizontal membersof the side bars, and whose lateral shoulders abut the surfacecontiguous to the slots, as shown and described.

3. In a truck-frame, the combination, with the sidebars having slots, asspecified, of the T cross-bars whose ends enter and bear in said slots,the lower or under flange of the cross-bars being cut away, thus forminga vertical shoulder which abuts the side of the adjacent side bar,substantially as shown and described.

4. In a truck-frame, the combination, with the side bars having slots,as specified, of the T cross-bars, whose ends enter said slots and haveboth lateral and vertical shoul lers,which abut the ends of the sidebars, as shown and described.

5. I11 a truck-frame, the combination, with the angle side and crossbars of the legs 0, made of fiat bar-iron and having their upper endsbent at a right angle and arranged with the outer sides of the angleportions in contact with the vertical. members of said side bars andwith the tenons of the cross-bars, and secured by the same bolts thatpass through the latter, as shown and described.

6. In a truck-frame, the combination, with the side and cross bars, ofthe legs 0, whose upper ends are bent at a right angle and bolted inplace, as specified, and whose middle portions are twisted axially, asshown and described, for the purpose set forth.

7. In a truck-frame, the combination, with the angle side bars andsuitable connecting cross-bars, of the bill having sockets to receivethe ends of said side bars, as specified.

8. In a truck-frame, the combination, with the side and cross bars, andthe bill having the pendent inner flange and central projection, of theaxle-pedestal whose ends are bolted in the angle of the said flange, asshown and described.
